I've just come across a recent discussion at the consciousagents site that looks as if it might have a bearing on Trehub's model of consciousness and brain.

Is that ^ you or Searle? I've put it in quotation marks because it has to be one or the other. The ambiguity continues in the sequence of your post below. Is it you writing in roman type and Searle in italics? If so or if not, which statements are whose? Who's speaking?
Is that claim -- that "there is a neurobiological explanatory level" -- meant to exhaust the inquiry into what consciousness is? Does it satisfy you, Steve, or even Searle?
Would you specify what 'road' you mean, and also specify what we are waiting for that might eventually 'appear'? Thanks.

Great point. I often wonder the same thing. I would propose that people become invested in their own positions to the extent that change means a loss of one or more elements including credibility, prestige, the comfort of one's own worldview, and possibly even material wealth, particularly if one has been lecturing and writing books for a living that would become irrelevant. Personally, as I've gotten older, I've found that my views tend to change less, not because of any of the aforementioned reasons, but because over time, I've distilled the applicable content from so many sources that new ideas that are substantial enough to compete are rare.
In this entire discussion, there has only been one significant change in my viewpoint, and that has been that I used to see no reason that artificial intelligence could not arise from sufficiently complex and powerful processing systems with the right programming, and that because such an intelligence would be indistinguishable from our own, notions of consciousness were largely irrelevant and in the domain of mystics and philosophers. I have completely changed my view on that because I realized at some point early on in the discussion that intelligence and consciousness may not simply go hand in hand.
Intelligence might be accomplished with the kinds of processors and programming we're used to in our computers, but consciousness might require different materials than our current line of microprocessors, and those materials might also need to be configured in very specific ways. That's why I began alluding to magnetism ( or sometimes light ) as an illustrative comparison, and when I heard Chalmers doing the same thing, I revaluated his views and came to appreciate them a lot more than I originally had, and that's why I've thanked you a number of times for introducing us to his ideas.
It's not surprising that confusing language should emerge from philosophical discussion ;-)
I'll attempt to clarify. Starting with your chosen example:
"We might roughly characterize the shared meaning thus: emergent entities (properties or substances) ‘arise’ out of more fundamental entities and yet are ‘novel’ or ‘irreducible’ with respect to them. (For example, it is sometimes said that consciousness is an emergent property of the brain.). Emergent Properties (Stanford Encyclopedia of Philosophy)
And we have Chalmers saying: "Consciousness is fundamental." and he compares consciousness to electromagnetism ( as in the Chalmers vidieo here: David Chalmers: How do you explain consciousness? | TED Talk | TED.com )
Now because Chalmers avoids thinking of properties as emergent, instead focusing on behavior, and doesn't explain ( at least anyplace I've seen ) that the word "fundamental" is a situation that arises out of irreducibility and that irreducibility is a key concept of emergentism ( as described above ), there is a sort of explanatory gap where the words "fundamental" and "irreducible" might be seen as synonymous and used in different contexts where their meaning should be differentiated, opening the way for the confusion that may be applicable here.
So, to fill in that gap, let's first accept that properties are also among the list of emergent phenomena and that electromagnetism is for all intent and purpose, an emergent phenomena, and there are many articles out there describing Emergent Electromagnetic Phenomena. For the sake of illustration; here's one example: http://digital.csic.es/bitstream/10261/117431/1/Electromagnetism.pdf
Putting this all together: Because consciousness is irreducible to anything other that itself, Chalmers sees it as something fundamental, which gets the basic point across, but opens the door for confusion between the words "irreducible" and "fundamental" in the context of the definition of "emergent", where consciousness can be seen as an irreducible property rather than irreducible behavior, and because Chalmers himself likens consciousness to emergent phenomena like electromagnetism, his viewpoint when looked at in the context of emergentism ( as defined above ), actually adds-up to a case for consciousness being an emergent property.
This idea IMO is very promising. It leads to a model that essentially says that we cannot reduce consciousness to the brain's matter, electricity, and EM fields, just like we can't reduce magnetism to the core, wire, or the current that makes up a magnet, yet overwhelming amounts of correlative evidence indicate that just like magnetism is dependent upon the existence of a magnet, consciousness is dependent on the existence of a brain, and therefore both appear to be emergent properties of specific types of systems. This points the way to discover relationships between the brain and consciousness that might facilitate practical applications.
On a related note with respect to Searle: It seems to me that Searle doesn't reject the idea that there is something we call consciousness that we identify with as our own personal experience of the world. It's that he sees consciousness as an integral part of the human brain in the same way that we might think magnetism is an integral part of a magnet. Each is integral to what we conceptualize the object to be. Personally, although that view is reasonable, I'm not entirely comfortable with it because it then requires that we redefine our general notions of what a brain is. For example the CPU in our PC is sometimes referred to as a brain, but it's not IMO conscious.
There are at least two levels of investigation of the problem of consciousness that we have been engaging in in this discussion. I'm sure in POM there are phrases for these two levels, but here are the phrases I'll use. The personal level and the ontological level.
It seems to me that the contribution of the phenomenologists is to provide a deep and rich investigation of consciousness at the personal level. In particular, MP shows us that contrary to what thinkers may have thinked, human perception and conception is is deeply, wholly embodied. So while we may think our thinks are objective and rational, the thoughts we think are really grounded in our humanness.
. . . ... so for those of us who aren't content with Searle's view, what underlies that discontent? For me it is an intuition or thought or recognition that consciousness is fundamental.
What I mean by fundamental is:
1. present at the beginning and ubiquitous - a feature, part of the basic furniture of the universe(s)
2. essential - it wouldn't be the universe it is without consciousness
3. irreducible
4. causal
these four interlock - it's hard to see that if consciousness were epiphenomenal (a-causal) that it could be essential, for example
I'm not happy with panpyschism when its presented in analogy to fields or particles (combination problem) - but such talk is very hard to get away from in our language ... Galen Strawson (the video or article above) - based on Russell's idea - that consciousness is the direct experience of the intrinsic nature of matter - the only direct knowledge we have - I like that and I think it's been overlooked, especially overlooked that it came from Russell. (@Soupie But I'm not saying that's my position!)
Not everyone accepts that the mind body problem is a legitimate "problem". Searle calls it a "false dichotomy" and similarly, I would say that the mind-body problem is a scientific problem to the same extent that there's a magnet-magnetism problem or a mass-gravitation problem. That's because science deals with the properties and behavior of the extant, not the nature of existence itself. That's the job of philosophers So the mind-body problem is only a "problem" for philosophers who choose to look at the co-existence of the mind and body as "problematic" in their context, and therefore since the nature of the problem in philosophical terms it's not relevant to science, I would question the relevance of your comment. Searle has no problem saying that we can take an objective and scientific approach to studying subjective experience. I agree.
We know our senses can be fooled and that what we perceive is a mental construct rather than an experience of the actual object being perceived, but this translates to: "Objective external reality isn't what we perceive it to be." not to "There is no objective external reality."
I included the time references ( I do review the content relevant to my posts even though it has been suggested by others at times that I don't )
Hoffman makes it quite clear at the start of the video that we don't perceive photons. We perceive the resulting mental experience that the photons initiate via the biology of our eyes and visual processing centers in the brain. He even has pictures that explain this in no uncertain terms. This is just fine. It's where he wanders off in his suggestion that all reality including spacetime and atoms and so on are also conscious constructs that he falls off the ledge.
If you're alluding to the mind-body problem, as the "problem", then it's not a "problem" for me because I accept that there are both minds and bodies and that they coexist in the universe as physical, in the sense that physical is not to be confused with "material", as in material vs. non-material. So for me, unless you are alluding to a different problem, there is no "problem to overcome". There are only relationships to study.
Not quite. Basically, I'm presupposing that all reality is physical in the sense that that everything that exists has properties and behaviors that lead to arbitrary relationships between them. This is a physicalist ( as opposed to materialist ) perspective because the "physical" isn't simply what we perceive to be "material". To be more specific there are branches of Physicalism and although I'm not sure where the philosophers would place me if they were able to see inside my head, it seems that I'm somewhere off in the realm of Emergentism. This seems to be a good overview: http://www.brynmawr.edu/biology/emergence/stephan.pdf
I don't actually "insist" that consciousness is physical but I do look at it as a physical phenomenon in the same way as we look at other phenomena like gravity, magnetism, etc. as being physical phenomena, and are equally perplexed as to the fundamental nature of their existence, but nevertheless have been able to map out their relationships to other materials and phenomena in a way that has proven to be very useful in many practical applications.
I'm not sure what would qualify in your comment as "beginning to support this claim.", but I would say that the number of posts I've contributed more than constitute a "beginning" and most are either based on or include accepted scientific information, particularly those that directly correlate brain function to conscious experience, and those that explore the idea that consciousness is an emergent property.
I'll close this post by saying that somewhat ironically, even though Chalmers criticizes emergentism, he also favors the idea that consciousness is something fundamental, which is also a feature of emergent phenomena. So Chalmers is actually endorsing emergentism, and his objection to it because it doesn't explain why consciousness should be accompanied by brain material and EM fields, is irrelevant. We may never be able to explain why consciousness should be accompanied by brain material and EM fields just like we may never know why objects should have mass.
Why type questions imply some purpose, and purpose is a concept that only has meaning to entities that are capable of understanding that concept, which is only a very small subset of all which appears to exist. So there is no reason "why" many things happen unless we invoke some omniscient God and claim it's all because of his or her divine will. In short: In the absence of a creator there is no "why" answer for fundamental phenomena. There is simply acceptance that it exists. Feynman goes through a rather long winded and painful explanation of this below as well:
Why Type Questions - Feynman
Maybe we need more knowledge. Maybe the question includes incorrect presuppositions. Maybe the question is absurd. Probably all three and more.It is out of the recognition of the actual situatedness of our own be-ing that we ask the question about Being . . . and find ourselves unable to answer it.

The Chalmers paper on Strong and Weak Emergence
http://consc.net/papers/emergence.pdf
... should make his position clear:
I think there is exactly one clear case of a strongly emergent phenomenon, and that is the phenomenon of consciousness.
Two other seminal papers by Chalmers are:
Consciousness and its Place in Nature in which our hero provides an expanded taxonomy of views on consciousness
and
Facing Up to the Problem of Consciousness
Maybe we need more knowledge. Maybe the question includes incorrect presuppositions. Maybe the question is absurd. Probably all three and more.
On a related note, @smcder has noted many times that the Hard Problem is only a problem for physicalists. While this was duly noted, I couldn't conceive of an alternative.
Thanks to comments by Michael Allen, I now find the notion that consciousness is constituted of, or emerged from, matter as being illogical. (Per his most recent posts, he doesn't see it that way.)
My fascination with the Hard Problem and the MUI aporia is due to the way in which they reveal our limited understanding of what-is. I find this exciting rather than upsetting.
That we are beings existing within Being.What do you think might be called "incorrect presuppositions" in our recognition of our own temporal, situated, be-ing and the further postulation of Being as extending beyond the horizons of what we can perceive and understand?
On what basis are you suggesting that our questions about being and Being might be "absurd"?
You've recently stated that you interpret phenomenology to be an emergentist account of consciousness. That is a physicalist account of consciousness, not an alternative to physicalism.Phenomenological understanding of the nature of consciousness and mind is the alternative I've offered, but for some reason you've been unwilling to explore it.
The Subset of Reality Problem
(1) Humans are experiencing beings.
(2) However, we can only infer this about others based on our own experiencing.
(3) Subsequently, we must infer the existence of a reality beyond all our individual experiencing.
(4) Ergo, experience is a subset of a larger reality.
What are some things that follow from this problem?
Explaining experience via the phenomena that appear within experience is unpossible.
Reality is much more vast and complex than our experience of reality, which is only a subset of reality.
Our (human) experience—how it feels, looks, smells, tastes—is only a small subset of reality, and thus not reflective of all of reality. Or even most of it.
There are causal forces at play within reality beyond our experience of reality, which is only a subset of reality.
There may be intelligent agents operating within reality outside of our experience of reality.
Etc.

I'm not sure in which sense the concept is misleading. And I don't see how you show that it is misleading.I think it is misleading to define human experience and thought as you do now as a "subset of reality," implying that 'reality' can be thought only from a position outside of our (and other living species') experience -- that is, from the location of a viewpoint that exists 'everywhere' or 'nowhere' and to which we have no direct access. How do we humans come to the point of such speculations? It must be the case that we think beyond the visible from our position within the visible aspects (phenomenal appearances available to to us) of the environment within which we experience our physical mileau and begin to think about it. In fact, subjective perspectives on 'what-is'/'reality' near at hand (and thence postulated to extend beyond the horizons of the locally visible) are precisely what initiates our acquaintance with and recognition of the objective pole of 'what-is' as sensed, experienced, and eventually thought about from the basis of our experience as a crossing of objective and subjective poles of reality.
However, as (individual) experience is but a subset of a larger reality, it seems likely that the preconditions of experience exist outside of experience.
That non-experiential reality is radically different than the subset of human experience (of reality) is a powerful idea and one that provides a new understanding of the hp aporia.
